Introduction

Nowadays, we have more and more device connected inside our house. On Linux OS there an easy command to list them all. It is named arp-scan. If you have Ubuntu, to install it, simply execute the following command :

1

sudo apt-get install arp-scan

Usage

If your machine is connected by wire :

1

sudo arp-scan--interface=eth0--localnet

If your machine is connected by wifi :

1

sudo arp-scan--interface=wlan0--localnet

Possible errors

you might not have eth0 or wlan0 defined and having the “ioctl: No such device” message. To find your network device :

1

/sbin/ifconfig

Names are listed on the left side . “lo” is not to be used as it is the local host, mainly used for test purpose.

Even if telnet is not popular as it used to be, it is really a good idea to cast an ASCII movie with this protocol. You can enjoy watching Star wars by launching the following command : telnet towel.blinkenlights.nl

The source is made of in three files : one for java and two for shaders.

I have to admit that it is a big step between GL1/GL2 and GL3/GL4 version. GL3 provides less graphical abstractions and more processing ones with shaders. For sure it is more powerful but the price of it is to write more line of code.

In order to avoid display flickering just add “-Dsun.awt.noerasebackground=true” parameter on the java options.

The informations are stored inside a cookie. The profiling quality is quite impresive. I just like it, because I have been aged 25-34. As I am 39, Google clearly identifies that I still young ; ) what about you ?
